BUTTING-TOOL.

Specification of Letters Patent.

Application filed October 15, 1919. Serial No. 330,879. a

improved construction wherein the tool will coact with a wedge forcausing a temporary bolt to be properly positioned when acting asclamping means for holding two sheet plates together. 7

A further object of the invention is to provide a tool which may be heldmanually against a bolt when applying a wedge thereto so as to cause thebolt to always remain in correct position as the wedge produces atightening action thereon.

In the accompanying drawing:

Figure 1 is a perspective view showing in a fragmentary manner, a pairof overlapped plates together with a bolt and a butting tool associatedtherewith, said butting tool disclosing an embodiment of the invention.

Fig. 2 is a top plan view of the butting tool shown in Fig. 1.

Fig. 3 is an elevation of a temporary clamping bolt.

Fig. 4 is an edge view of the tool shown in Fig. 5 is a front view ofthe tool shown in In producing the butting tool forming the invention,it has been aimed to overcome certain objections which have arisen whenapplying a temporary bolt for holding plates together. In buildingships, where either the side plates, deck plates or other plates areriveted together the plates are first bored or punched before they arebrought into position. Originally an ordinary bolt and nut was used atintervals for rigidly clamping these plates together so that a reamingtool could be used for truing up the holes not occupied by the temporarybolts. After this has been done hot rivets are then placed in positionand riveted down in the usual manner after which the temporary bolts areremoved and the holes trued and rivets are then placed in the holesoccupied by the temporary bolts. In order to expedite the applicationand removal of the ble.

temporary bolt is sometimes inclined to one Patented Sept. I Z 1920...

temporary bolts a new form of bolt, shown in Fig. 3 is provided, thesame-being formed with a head 1 and a body 2 formed with a. slot 3extending for almost the full length of the body. This bolt isplacedin-position as shown in Fig. 1 for temporarily bolting the plates & and5 together. The wedge 6 acts against the bolt and against a suitablewasher 7 for tightening the bolt and clamping the plates 4: and 5 inposition, and the wedge is driven into the slot as far as possi-Indriving the wedge 6 in place the side and thereby shifts slightly theplates 4 and 5. This shifting is not noticed at first and consequentlyproduces a bad job, which must be rectified in some manner. When thetemporary bolt is to be removed the wedge 6 is merely knocked out andthe bolt may be easily removed by hand after which the 'hole occupiedthereby -may be reamed and supplied with a rivet in the usual manner. Toprevent the inclination of the bolt when applying the wedge 6the'butting tool embodying the invention has been produced,

: which is positioned as shown in Fig. 1 during the time that the wedge6 is being driven into the bolt. The butting tool is provided with ahandle 8 and a head 9 formed in the upper part with a groove 10extending parallel with the sides of the head 9 while on the bottom ofthe head inclined or diverged grooves 11 and 12 are formed to take careof the angle of the wedge 6 when the temporary bolt is near an uprightor wall. The bolt engaging face of the head 9 is provided preferablywith annular face sections 13 and 14. merging ata central line 15. Theseface sections may be roundedybut-are preferably fiat so as to engage thebody 2 of the bolt at a distance from the central line 15.

In operation, the body 2 of the temporary bolt is dropped into any tworegistering plates 4E and 5, washer 7 applied thereto and then the wedge6 placed in position manually. The head 9 is then arranged, for instanceas shown in Fig. 1, and the wedge 6 driven home. The action of thehead?) will be to maintain the bolt 2' in correct position, or at aright angle to the plates land 5, whereby the holes will always bemaintained in proper alinement. This arrangethe plates 4 and 5 tightlytogether Without lllJlllIng either the plates, the split bolt, or

' any of the-associate parts.

. What I claim is:

l. A butting tool comprising a head formed with a bolt receiving face, aWedge guide, and a handle extending from said head. i

2. A butting tool comprising a holding member, a head formed With agroove on one face, a plurality of grooves 011 the opposite face, and aconverging bolt receiving face extending substantially at right anglesto said grooves.

3. A butting tool comprising a handle in use. 7 ROBERT WVILLIAM AYLING.
